Revision as of 17:00, 27 March 2012

This documents track potential backward compatibility issues for Joomla 3.0 and Joomla Platform 12.1 which is included in Joomla 3.0. Listed are issues which potentially break extensions. Please help making this document complete.

Platform

The platform removed a larger number of deprecated classes and methods. For most extensions written for Joomla 2.5 the required changes should be reasonably small. Note that there are still deprecated classes in the platform that will be removed in future versions, developers should stop using them where possible.

General changes

Appending ?no_html to an URL to get a RAW view is not supported anymore (this was an old Joomla 1.0 feature)

The DS constant has been removed. If you really need it you can use DIRECTORY_SEPARATOR instead

Many more function arguments have been type hinted, including existing classes. Make sure you're always passing values of the correct type.

PHP 5.3 is now required

register_globals = on is not supported anymore

The name of modules now have to start with mod_

The module cacheing option "oldstatic" has been removed.

Extensions need to set the registeredurlparams now, the fall back on the URL has been removed.

Changes to extension installation

Use of the <install> base tag (from 1.5) is no longer supported; use <extension> instead

Suppport for install_script and uninstall_script, and the methods com_install and com_uninstall in these scripts, has been removed; use scriptfile instead

In language extensions, support for client="both" has been removed; package each client as a separate extension and optionally bundle them as a package extension instead

File paths for plugins no longer support the old 1.5 method (i.e. plugins/system/cache.php); each plugin must be in its own folder (i.e. plugins/system/cache/cache.php)

Changes to Components

In admin components the admin.*.php and toolbar.*.php are not automatically included anymore. This was a Joomla 1.0 legacy feature.

Moved files

All classes listed here should now be autoloadable. Explicit requires and includes have to be modified or removed.
